At present we have only SSU operational. The aim of this run is twofold. First - we do an SSU alignment by scanning the momentum of the incoming beam (equivalent to scanning current, but easier on the magnet). Second we measure pion impurity in the incoming beam (TKU recon will be suspect at momentum > 200 - we do the best we can).
Note that diffuser data was taken last night during the night shift.
Task 9: SSU alignment¶
Try doing two sets of this before midnight...
